What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Diagnostic laparoscopy (DL) is increasingly used in the preoperative evaluation of patients with peritoneal metastasis (PM) who are considered for cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC). Cross-sectional imaging has limited accuracy for assessing small-bowel and mesenteric disease, which are key determinants of resectability. DL may improve patient selection and reduce the frequency of nontherapeutic laparotomy. Aim: We aimed to summarize current evidence on the feasibility, diagnostic performance, and clinical impact of DL in patients with PM undergoing qualification for CRS-HIPEC. Materials and methods: A narrative review of the literature was conducted. The studies were identified through a search of the PubMed, MEDLINE, and Scopus databases, supplemented by manual reference screening. Eligible publications included prospective retrospective cohorts, multicenter studies, diagnostic accuracy trials, and reviews reporting outcomes of DL for CRS-HIPEC. The data were synthesized thematically. No meta-analysis was performed. Results: A total of 29 studies were included. Across 3632 procedures, DL was successfully completed in 98.3% of the patients. As many as 1034 individuals (28.5%) were excluded from CRS-HIPEC based on laparoscopic findings. Reduction in the frequency of futile laparotomy was reported across various tumor types, including colorectal metastasis (approximately 12%-17%), gastric cancer (approximately 30%), and ovarian cancer (approximately 58%, when combined with computed tomography findings). Peritoneal cancer index underestimation occurred in 40%-63% of the mixed cohorts, mainly due to limited visualization of the small bowel. Positive predictive value for complete cytoreduction ranged from 80% to 95%. Major morbidity was below 2% in most series. Conclusions: DL is a safe and accurate staging tool that improves patient selection for CRS-HIPEC, reduces the need for nontherapeutic laparotomy, and supports timely initiation of appropriate therapy. It should be considered a key component of contemporary staging pathways for PM.
